MACHINE FO R FINISHiNG OPEN-ENDED GLASSWARE.

SPECIFICATION formingpart of Letters Patent No. 230,543, dated July 27, 1880.

Application filed May 31, 1879.

7'0 all whom it may concern:

Be it known that I, JOSEPH J. GILL, of Stenbenville, in the county of Jefferson and State" of Ohio, have invented certain new and useful Improvements .in Machines for Finishing Open-Ended Glassware; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyin drawings, and to letters of reference markerv thereon, which form a part of this specification.

My invention is specially adapted to opening out and finishing lamp-chimneys, goblets, bottle-necks, jars, and such like articles of glassware; and it consists of the combination of certain mechanical elements, as hereinafter fully described, and particularly indicated in the claims.

In the drawings, Figure l is a side view of my machine; Fig. 2, end view; Fig. 3, sectional view lengthwise of the machine; Fig. 4, cross-section on line as 00, Fig. 1.

The letter 13 represents a shaft journaled on bearingsi i. One end of the shaftis made hollow a portion of its length. (Shown fully in Figs. 3 and 4.

g is a slot through the shell running parallel with the axis. L is a cross-piece or support permanently attached to the end of the shaft at right angles. 0 is an adjustable collar havin g set-screw h to secure itin place on the shaft.

E is a pintle or stem, to one end of which is rigidly attached a face-plate or disk, A. The inner end of this stem is made conical and has a conical seat in the bore of the shaft B.

fis an annular groove on the stem, and h is a pin in the side of the shaft, which works in the groove and prevents longitudinal displace ment of the stem. A spiral curved groove or slot, 6, is formed on the surface of the stem.

D is a movable sleeve on the shaft B, having a pin or stud, 7L which moves in the line of the slot 9 and projects down into the spiral groove 0. The longitudinal movement of the sleeve causes a rotary movement of the stem and face-place attached thereto.

O is a lever fnlcrumed to the frame of the machine, havinga forked end, which engages lengthwise movement required to rotate the face-plate. p is a connecting-rod attached to any suitable operating mechanism; K, platform or table of machine. F is the drivingpulley. I) b are lever-arms secured to crosspiece L by means of aslot-and-pin connection, a, and are pivoted to the face-plate near the periphery at a a a a are tool-blades secured to the end of the lever-arms. These tool-blades open outward from each other parallel by a partial rotary motion of the face-plate A in the manner shown by the dotted lines in Fig. 2.

m m are slots in the face-plate for the reception of exterior forming-tools, h 76, which can be made adjustable toward and from the cen ter by means of a screw-thread and nut.

The working-faces of both the interior finishing-tools and the exterior forming-tools can be of any desired shape from that shown to permit of a variety of styles and patterns being made.

In operating the machine power is applied to the shaft B, whereby the tool-head is made to revolve quite rapidly. The operator places the blow-pipe, with the bowl of the article to be opened, upon acouple of guide-rests in front of the machine on a line with the axis of the shaft, and gradually pushes the article toward the opening-tools, which enter the perforation in' the end of the bowl. The operator then applies power to the shifting-lever, either with a foot-treadle or in any other suitable way, and causes a length wise movement of the sleeve D, with pin its on the shaft, which imparts a retary movement of the stem and face-plate, throwing the tool-blades outward from the center to the desired diameter, the collar 0 serving as a stop for the sleeve, and thus regulate the size of the opening to be made.

The exterior forming-tools are serviceable for finishing the tubular base of lamp-chimneys and such like articles, and are also applicable to articles having fanciful shapes upon their outer surface.

I am aware that expansible tools carried on a rotating shaft and expanded from a common center by a sleeve sliding on such shaft, the movement of which sleeve may be limited to adjust the expansion of the tools, is old; and

' in a groove, f, on the sleeve D, to give the also that it is not new to cause a single finishin g-tool while moving progressively away from a fixed center to traverse the interior surface of the article in course of formation.

I am aware that the combination of arotating shaft carrying a tool-head and a central independent head, to which the opening-tools are pivoted, whereby the said tools are caused to expand from a common center in the arcs of circles, is old; that the method of opening and shaping hollow glassware, consisting in pressing it over or upon an expansible or expanding former without external pressure, either the former or article, or both, being r0- tated, as well as the use of mechanism for automatically limiting the expansion of the former, is likewise old, and do not claim the same; but,

Having described myinven tion, what Iclairn, and desire to secure by Letters Patent, is-- 1. In a machine for opening and finishing glassware, the combination of a rotating shaft, B, carrying a tool-head, L, of lever-arms b I), connected by pins and slots to said head and carrying the tools a a, and of a central independent disk, A, capable of partialrotation and connected to the arms b, whereby the tools a a are expanded, as set forth.

2. In a machine tor opening and finishing B, carrying a tool-head, L, of lever-arms b b, connected by pins and slots to said head and carrying the tools a a, and of a central independent disk, A, capable of partial rotation and connected to the arms b, in combination also with tools k k, as set forth.

3. [n a machine for opening and finishing glassware, the combination of the tool-blades a a, attached to levers b b, disk A, attached to stem E, having spiral groove 0 and annular groove f, shaft B, having longitudinal slot g, pin h, tool-support L, collar 0, having setscrew k movable sleeve D, and pin h, substantially as herein shown, and for the purposes set forth.

In testimony thatI claim the foregoing as my own I hereunto afIix my signature in presence of two witnesses.

JOSEPH J. GILL.
